AT1 trailer, £249.99,

The single-seater aluminium AT1 is a top of the range adventure trailer — there’s also the AT3 alloy two-seater for £219 or the  ST3 steel two-seater for £169. It hitches onto the rear axle of any mtb or road bike and a 20in wheel means that it rolls well and steers easily. The child has good visibility with large side windows and a front window that can be open so you can hear them shouting ‘are we nearly there yet’ or closed to the elements with mesh or clear roll-down windows. It has ample storage, folds easily and takes children up to 18kg/40lb (approx age 3-4).

PROS: lightweight, value
CONS: child out of sight line
